Sony FCB camera block
The scanning mode of the camera refers to the scanning mode used by the camera during imaging. There are two main types: Progressive Scan and Interlaced Scan.
A basic introduction to scanning systems
Progressive Scan:
Progressive scanning means that the camera scans each pixel line of the image in sequence, and the entire image is scanned at one time. Progressive scanning can provide a clearer image, because the entire image is completed in one scan, and there is no interlace and jitter phenomenon caused by interlaced scanning. This scanning method is suitable for shooting static pictures or high-speed dynamic scenes, which can present a clearer and more stable image.
The FCB-ER9500, SONY’s first 4K60P integrated camera movement module, is expected to be fully available in summer 2024.
The “P” in this “4K60P” refers to progressive scanning, which means that the FCB-ER9500 can shoot continuous images at a resolution of 4K, with 60 progressive scans per second.
Interlaced Scan:
Interlaced scanning means that the camera scans the odd rows of pixels of the image first, and then scans the even rows of pixels, two scans to create a complete image. Interlinear scanning can reduce the amount of data transmission and improve the speed of image transmission, but the picture may be blurred and jitter when shooting moving pictures. Interlaced scanning is generally suitable for traditional television systems or low-resolution cameras, but is less suitable for scenes with high definition video requirements.
The SONY FCB-EV9520L HD integrated camera supports both 1080P60 and 1080I60, so it supports both progressive scanning and interlaced scanning. Whether the FCB-ER9500 supports interlaced scanning is subject to the document released by SONY.
The relationship between scanning standard and image quality:
The scanning standard of the camera directly affects the quality of the image taken. Progressive scanning usually provides a sharper and more stable image and is suitable for high definition video shooting or scenes that require high image quality.
While interlaced scanning has advantages in transmission speed, it may not be as good as progressive scanning in terms of image quality. Therefore, it is very important to choose the suitable scanning system to obtain satisfactory shooting effect.
When selecting a camera, the user needs to determine the appropriate scanning system according to the shooting needs and scene requirements to obtain the best image quality.
Contrast between progressive scanning and interlaced scanning
1. Progressive scanning:
1.1 Principles and Features:
Progressive scanning means that the camera scans each pixel line of the image in sequence, and the entire image is scanned at one time. This scanning method ensures that every pixel of the image is scanned, resulting in a clear and stable image.
The principle of progressive scanning is to scan the entire image area step by step, and then combine these scanned pixels in order to form a complete image.
1.2 Advantages:
Progressive scanning can provide a clearer and more stable image, without interlacing and jitter caused by interlacing. Suitable for shooting static images or high-speed dynamic scenes, can present more delicate details.
1.3 Disadvantages:
Progressive scanning requires more data transfer and processing power, and may take up more resources than interlaced scanning. In the case of some low-bandwidth transmissions or low-performance processors, delays or stalling may occur.
1.4 Application Scenario:
Progressive scanning is suitable for scenes that require high image quality, such as high-definition video shooting, film production, etc. It is also suitable for static images or high-speed dynamic scenes that require detail and clarity.
2, interlaced scanning:
2.1 Principles and Features:
Interlaced scanning means that the camera scans the odd rows of pixels of the image first, and then scans the even rows of pixels, two scans to create a complete image. This scanning method can reduce the amount of data transmission and improve the image transmission speed, which is suitable for the scene with high transmission speed.
2.2 Advantages:
Interlaced scanning can improve the image transmission speed and reduce the data transmission amount, and is suitable for low-bandwidth transmission or scenarios requiring high transmission speed.
2.3 Disadvantages:
Interline scanning may cause blur and jitter when shooting moving pictures, and it is not as good as progressive scanning to present clear and stable images.
When selecting progressive scanning and interlace scanning, users need to choose according to the specific shooting needs and scene requirements to obtain the best shooting effect.
